Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment for penstocks, and particularly relates to a transportation support device for a large-diameter penstock on a flatbed truck. Background Art

[0002] The diameter of the penstock pipe section of a certain hydropower station is relatively large, reaching about 7 meters, which is much larger than the width of the cargo bed of the transportation flatbed truck. Moreover, the finished product storage site after the steel pipe is manufactured is far from the installation location of the diversion tunnel of the power station, and it is necessary to transport it to the installation site by a flatbed truck.

[0003] There are many daily passing vehicles on the road and the road width is limited, resulting in that when the vehicle loads the penstock for transportation, it usually needs to occupy the oncoming lane, and it is also necessary to contact the local relevant traffic management department to conduct traffic control on both sides of this section of the transportation road in advance, only allowing the penstock transportation vehicle to pass. During the whole process of steel pipe transportation, the vehicle speed should not be too fast and needs to be carried out at a uniform and stable speed, resulting in a relatively long time for traffic control for the round trip.

[0004] Due to the limitation of road conditions, the whole transportation process is very cumbersome, greatly reducing the transportation efficiency and prolonging the construction period. Content of the Utility Model

[0005] The purpose of the utility model is to provide a transportation support device for a large-diameter penstock on a flatbed truck to solve the problem of low transportation efficiency on narrow and restricted roads.

[0006] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0007] A transportation support device for a large-diameter penstock on a flatbed truck, including a flatbed truck, which includes a support frame, a left support structure and a right support structure;

[0008] The support frame is arranged on the cargo bed of the flatbed truck;

[0009] The left support structure includes a first support arm, a second support arm, a first vertical mounting rod and a second vertical mounting rod; the bottom end of the first vertical mounting rod is connected to the left part of the support frame, and the top is provided with a first connection hole; one end of the first support arm is hinged to the front end of the left part of the support frame, and the other end is provided with a second connection hole matching the first connection hole; the second vertical mounting rod has the same structure as the first vertical mounting rod and is arranged behind the first vertical mounting rod; the second support arm has the same structure as the first support arm and is arranged at the rear end of the left part of the support frame;

[0010] The right support structure is the same as the left support structure and is arranged on the right part of the support frame.

[0011] As a further technical solution of the above solution, buffer rubber pads are provided on the surfaces of the first support arm, the second support arm, the support frame in contact with the penstock.

[0012] As a further technical solution of the above solution, a plurality of lifting lugs are provided on the support frame.

[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects: the utility model supports the penstock through the support frame, the left support structure and the right support structure, ensuring the stability of the transportation process; after the transportation, the first support arm and the second support arm of the left support structure and the right support structure can be retracted above the flatbed truck, and it does not affect the normal driving of the flatbed truck on narrow roads, improving the transportation efficiency of the penstock.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model, so as to have a further understanding of the concept, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought by the present utility model.

[0020] As Figures 1 to 4 shown, a large-diameter penstock flatbed truck transportation support device includes a flatbed truck, and includes a support frame 1, a left support structure 2 and a right support structure 3;

[0021] The support frame 1 is arranged on the cargo board of the flatbed truck 4;

[0022] The left support structure 2 includes a first support arm 21, a second support arm 22, a first vertical mounting rod 23, and a second vertical mounting rod 24; the bottom end of the first vertical mounting rod 23 is connected to the left part of the support frame 1, and a first connection hole 25 is provided at the top; one end of the first support arm 21 is hinged to the front end of the left part of the support frame 1, and a second connection hole 26 matching the first connection hole 25 is provided at the other end; the second vertical mounting rod 24 has the same structure as the first vertical mounting rod 23 and is arranged behind the first vertical mounting rod 23; the second support arm 22 has the same structure as the first support arm 21 and is arranged at the rear end of the left part of the support frame 1;

[0023] The right support structure 3 is the same as the left support structure 2 and is arranged on the right part of the support frame 1.

[0024] In this embodiment, first, the support frame 1 is arranged on the cargo bed of the flatbed truck 4. The first support arm 21 and the second support arm 22 are opened, and the pressure steel pipe is hoisted and placed on the overall support structure formed by the first support arm 21, the second support arm 22, and the support frame 1. At this time, the pressure steel pipe is in a flat state, which is convenient for transportation; after the flatbed truck 4 transports to the construction area, the pressure steel pipe is removed; at this time, the first support arm 21 and the second support arm 22 are rotated. After aligning the first connection hole 25 and the second connection hole 26, bolts are used to pass through the first connection hole 25 and the second connection hole 26 and then fixed, so that the first support arm 21 and the second support arm 22 are retracted above the cargo bed of the flatbed truck 4. At this time, both the left support structure 2 and the right support structure 3 are retracted above the cargo bed, and the flatbed truck 4 can drive normally without the need to communicate and arrange traffic control, improving the transportation efficiency.

[0025] As Figure 2 and Figure 4 shown, as a preferred embodiment, buffer rubber pads 5 are provided on the surfaces of the first support arm 21, the second support arm 22, the support frame 1 in contact with the pressure steel pipe. In this embodiment, buffer rubber pads 5 are arranged on the contact surfaces of the pressure steel pipe. While buffering the impact force, the buffer rubber pads 5 can increase the friction, so that the pressure steel pipe is placed on the support frame 1, the left support structure 2, and the right support structure 3 more stably, ensuring the stability of the transportation process.

[0026] As Figure 2 and Figure 3 shown, as a preferred embodiment, a plurality of lifting lugs 6 are provided on the support frame 1. In this implementation, the support frame 1 is detachably arranged on the flatbed truck 4. After the overall support frame 1 is hoisted onto the flatbed truck 4 by a hoisting device, it is fixed by means of bolts, etc.; after use, the support frame 1 can be removed through the lifting lugs 6 for maintenance or replacement.

[0027] The "connection" and "fixation" mentioned in the description of the present utility model can be fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present utility model should be understood according to the specific circumstances.
